Description

Technical Field

[0001] This utility model relates to the field of welding inspection technology, specifically a welding inspection device. Background Technology

[0002] Welding inspection refers to the inspection of welding results. Its purpose is to ensure the integrity, reliability, safety, and usability of the welded structure. In addition to the requirements for welding technology and welding process, welding inspection is also an important part of the quality management of welded structures. In order to ensure that the pipeline can work normally, the welded parts of the pipeline need to be inspected after the pipeline welding is completed.

[0003] A search revealed a utility model patent in China with patent publication number CN215894222U, which discloses a welding strength testing device. The device is broadly described as including a pusher, one end of which extends into a pipe and is hinged to one end of at least two push rods. The push rods are evenly distributed around the circumference of the pusher, and the other end of each push rod is hinged to a corresponding push plate. The outer wall of each push plate abuts against the inner wall of the pipe weld. During use, an axial alignment frame is used to ensure that the pusher is coaxial with the pipe, thereby guaranteeing that the pressure applied by all push plates to the pipe weld is uniform. This makes the test results more accurate. By adjusting the length of the connecting rod, the test requirements of pipes with different diameters can be met. At the same time, the connecting rod is equipped with scale lines to ensure that the length of each connecting rod is consistent after adjustment, and to ensure that the pusher is coaxial with the pipe. However, the above device still has some shortcomings. For example, the above device is relatively cumbersome, time-consuming and labor-intensive to install and use. It is not convenient to quickly and accurately make the push plate contact the pipe weld. Moreover, multiple points are generally tested during the test. The above device is also relatively cumbersome to adjust during the test, resulting in low work efficiency. Therefore, we propose a welding test device. Utility Model Content

[0024] Example

[0025] Please see Figures 1-4 A welding inspection device, comprising:

[0026] Base 1;

[0027] The testing mechanism is mounted on base 1 and includes support plate 1 (2) and support plate 2 (3). Both support plate 1 (2) and support plate 2 (3) are fixedly connected to base 1. Two rotating rollers (4) are rotatably connected between support plate 1 (2) and support plate 2 (3). A motor (5) is mounted on support plate 1 (2), and the output end of motor 5 passes through support plate 1 (2) and is fixedly connected to one of the rotating rollers. Pipes (6) are placed on the two rotating rollers (4). A controller (7) is mounted on support plate 2 (3). An opening is formed in support plate 2 (3), and an electric cylinder (8) is installed through support plate 2 (3). The output end of electric cylinder (8) is located within the opening and is fixedly connected to a lifting block (9). An electric cylinder (9) is installed through lifting block (9). Cylinder 2 10, the output end of which is fixedly connected to a fixing block 11, has two mounting slots, in which an electric cylinder 3 12 is installed. The output end of the electric cylinder 3 12 is fixedly connected to a top plate 13, on which a camera 14 is installed. Multiple telescopic rods 15 are fixedly connected to the top plate 13, and a top block 16 is fixedly connected to each of the telescopic rods 15. A pressure sensor 17 is installed on the top plate 13. The electric cylinders 1 8, 2 10, and 3 12 are used to fix the top block 16 at the weld joint of the pipe 6. The pressure sensor 17, controller 7, and camera 14 are used to detect the pipe 6, improving the detection effect.

[0028] Two sliding grooves are provided in the opening, and sliders 18 are slidably connected in the sliding grooves. The lifting block 9 is fixedly connected between the two sliders 18 to improve the stability of the lifting block 9 when it is raised or lowered.

[0029] A spring 19 is fitted on the telescopic rod 15 to lift the top block 16, preventing the top block 16 from pressing on the pressure sensor 17 when not in use.

[0030] Multiple telescopic rods 20 are fixedly connected inside the mounting slot. The other end of the telescopic rods 20 is fixedly connected to the top plate 13 to improve the stability of the top plate 13.

[0031] A fixing plate is fixedly connected to the base 1, and a soft pad 21 is fixedly connected to the fixing plate to protect the pipe 6 and prevent the pipe 6 from rolling out on the other side.

[0032] An inclined plate 22 is fixedly connected to the base 1, and an adhesive layer 23 is fixedly fitted on both rotating rollers 4 to protect the pipe 6 and prevent damage to the pipe 6 from violent collisions.

[0033] It should be further explained that the pressure sensor 17, motor 5, electric cylinder 8, electric cylinder 10, electric cylinder 12, camera 14, and controller 7 in this embodiment are conventional devices known to those skilled in the art and available on the market. Models can be selected or customized according to actual needs. In this patent, we only use them without improving their structure and function. Their setting method, installation method, and electrical connection method can be easily explained by those skilled in the art by following the instructions for use. They will not be described in detail here. The pressure sensor 17, motor 5, electric cylinder 8, electric cylinder 10, electric cylinder 12, camera 14, and controller 7 are equipped with matching control switches. The installation position of the control switches can be selected according to actual usage requirements to facilitate operation and control by the operator.

[0034] In summary, the working principle and process of this welding inspection device are as follows: First, the device is placed at the desired location. Then, the pipe 6 is pushed onto the two rotating rollers 4 via the inclined plate 22. At this point, the controller 7 activates electric cylinder 8, which moves the lifting plate and electric cylinder 10, aligning electric cylinder 10 with the center of the pipe 6. Then, the controller 7 activates electric cylinder 10, which moves the fixed block 11, camera 14, etc., into the pipe 6. Users can then view the internal condition of the pipe 6 through the controller 7 and camera 14. When the welding point is reached, electric cylinder 10 is deactivated. The controller 7 then activates two electric cylinders 12, which move the top plate 13, pressure sensor 17, etc. At this point, the two top plates... Block 16 will simultaneously press against the weld joint of pipe 6, causing spring 19 and telescopic rod to retract. Block 16 will then press against pressure sensor 17, allowing for the detection of the weld joint of pipe 6. The pressure value can be viewed more intuitively through controller 7. When the qualified pressure value is reached, electric cylinder 12 is controlled to retract, and motor 5 is started through controller 7, causing one of the rotating rollers 4 to rotate. This allows the rotating roller 4 to rotate pipe 6, while the other rotating roller 4 follows suit. This allows for quick switching of the weld joint detection position, facilitating the detection of other locations at the weld joint. It also allows for visual inspection of the weld joint of pipe 6 through camera 14, improving the detection effect. This device is suitable for pipes 6 of different specifications, is simple and quick to operate, and has high practicality.

[0035] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
